My invention relates to improven'ients in tions 16 so that air can be drawn from the 55 pipe and cigar lighters and has for its obback of the casing through the perforations ject to provide a lighter which will thor- 1a in the front side. 18 is a handleentering oughly ignite a cigar without having the a socket 19 secured to the casing wall.

The removable side has an up shown in Fig. l so as to substantially cover 95 turned edge 8 engaging a slightly outturned the perforation 36 as shown in Fig. 5 and edge 9 on the casing body, while the oppoyet be spaced apart as shown in Fig. 4.

After the removable unit is inserted and The removable side of the casing is prothe front side of the casing is applied the vided with a group of perforations l l lighter is in condition for use.

against which the end of a cigar or the mouth The conductors leading to the handle are of a pipe is laid when the lighter is in use. connected to a plug a1 adapted to be placed The rear portion of the casing, preferably in circuit with a source of current, such as the rear side, is also provided with perform an ordinary lighting socket, and when the and the element cools off.

switch 22 in the handle is closed by pressing the button, the circuit through the resistance element is closed. The several portions of the resistance element which are in front of and in back of the perforation in the insulating base and are thus in filament form being out of contact with the base and completely surrounded by air. They therefore become quickly incandescent and highly heat the air surrounding them, so that the casing constitutes a chamber containing in its central portion highly heated air. This air, when suction is applied to the openings of the front face by the application of the cigar or pipe, is drawn toward the tobacco and causes the same to i nite quickly and thoroughly. As soon as the button in the handle is released the circuit is broken at the switch The action is quick because the active parts of the resistance not being in contact with any solid cooling substance, but being in filament for i, are quickly brought to incandescence and there being a substantial group of these incandescent filaments a considerable volume of air is quickly brought to a high heat.

In'order to guard against possible danger la" the lighter down while the switch L I provide a laterally protect- I g i which is affixed to the casing projecting on all sides, and so situated that the center of gravity of the lighter as a whole is on the handle side of the guard. I preferably place this guard on the side of :he casng' which is adjacent to the handle, as shown.

The resistance element 38 is preferably made of the well known nickel-chromiumiron wire commonly used in electric heating devices.

As will be evident to those skilled in the art, my invention permits of various modifications without departing from the spirit hereof or the scope of the appended claims.

hat I claim is:

1. In a cigar lighter the combination of a casing having a removable front face, forwardly projecting contacts located in the rear of said casing, and conductors leading therefrom and adapted to be connected to an electrical circuit, a removable heating unit comprising a skeleton base of insulating material having on its rear face projecting contacts adapted to slicingly engage said forwardly projecting contacts, and a resistance element carried by said base having its ends connected to said base contacts and having portions exposed to air drawn through said skeleton base, said casing having perforations in the central portion of the front face thereof and in the rear of said resistance element.

2. In a llghter the combination of a casing, a heating unit therein comprising a skel- 7 3. A casing having two parallel sides, one

of which is fixed and the other of which is removable, and a wall to which said sides are secured, a handle projecting from said wall, two conductors passing through said handle and having their inner ends removably connected to said fixed side, terminal contacts connected to said conductors respectively, and a removable heater unit comprising a skeleton base having a large open ing for the passage of air and carrying rear contacts adapted to engage said terminal contacts and a resistance element connected to said rear contacts having portions cross ing said opening, said case having perforations in said front side and in the rear of said resistance element.

l. In a cigar lighter, a casing having a suction opening in the central portion of its front face, a heating unit in said casing comprising a base having a large openlng for the passage of air therethrough in line With said suction opening, and a heating element supported on said base having a group of parallel active filamentary portions crossing said openings in said base and face so as to be entirely surrounded by air.

5. In a cigar lighter, a casing having a suction opening in the central portion of its front face, a heating unit in said casing comprising a base having a large opening for the passage of air therethrough in line with said suction opening, and a heating element supported on both sides of said base having a group of parallel active filamentary portions in line with and crossing said open ings in said base and face so as to be en tirely surrounded by air, said filamentary portions being part on one side and part on the other side of said base, the portions on the opposite sides being in staggered relation.

In testimony whereof, I have signed my name to this specification this 17th day of April, 1925.
